I think that you are right. Your thoughts are a better way forward but if people think that once things that affect AR are tried then they are permanent then I don't know where to go from there in terms of using current science to help people. I think looking at body hair/beard/scalp hair as one thing is closer to the murcine modeling and leaves us to some extent puzzling over things like manes, antlers and why whales largely lack body hair like we do. Someone articulated this really well earlier with respect to Kurt Russell and others with I would say excellent male hair that looks good long while also having excellent beards. We know they exist and they are nowhere near androgynous but what can we extract from this to help others? How many genes are in play? What happens if a person has three, four, five, six, versus none? T/DHT ratio? How does that matter? Is all body hair, beard hair and scalp hair after puberty more or less in stasis equilibrium between females and males? Meaning if we change one thing, then we alter another. Many transgender females lose most or all beard growth like Bridge did but most of us need some beard removal. What about minoxidil beards? Do they alter any hair balances? Why is side burn hair a transition area instead of just being beard hair.
The main benefit of living this on both ends is seeing all of the different components holistically which is hard to do if one never experienced the other. My interest is not to establish that estrogen is all that works. We know that but could altering things a tiny bit cause a cascade of improvements? Ultimately using whales might be more interesting than murcine animals but that's about the only other partially naked mammal really so other animals lack three different types/areas of different hair types in terms of texture and being terminal/vellus vel non.
For people not in fear of permanent AR disruption, I find what you are mentioning to be the best hope and there seems to be a divergence in XY's going off HRT in terms of whether dutasteride maintains well or whether hair implodes right away like it seems to when people stop microneedling for two months. A lot of these things that could be tried in terms of cycling are fascinating in terms of how they affect muscle growth and strength. I found spironolactone plus low dose estrogen to be far, far more stereotypically feminizing that even ultra high dose estradiol. I couldn't mow the lawn or get it started or open bottles of soda that had the cap on too tight and desisting from spironolactone resolved all but the normal variation expected from estrogenic environments meaning yes, diminution in strength but chicks have muscles too and some of them are far stronger even pound for pound than some XY's.
